I've been trying several variants of:
qemu-system-ppc -M prep -nographic -hda "ext2.img" -kernel "zImage" \
-append "rw init=/tools/bin/sh panic=1 PATH=/tools/bin root=/dev/hda
console=/dev/ttyS0"
My miniconfig is attached. (You can make a full-sized .config out of it with
"make allnoconfig KCONFIG_ALLSYMS=miniconfig-linux", I still need to get the
miniconfig patch in so there's a better UI.) I'm trying to boot the zImage
file that produces.
Unfortunately, I've never managed to boot a ppc kernel under qemu
with -kernel. I've got to be doing something wrong, but I don't know what it
is. Could you offer any hints?
Here's the output I get:
Could not configure '/dev/rtc' to have a 1024 Hz timer. This is not a fatal
error, but for better emulation accuracy either use a 2.6 host Linux kernel
or type 'echo 1024 > /proc/sys/dev/rtc/max-user-freq' as root.

It's not getting _to_ the kernel. (I tried booting vmlinux instead of
bzImage, but it made no difference.)
Thanks,
